VENTILATING FAN.

Application med May V1e, 1924.,y serial No. 714,369.

To all whom it may concern Beit known that I, WILLIAM BUCCIm Y a citizen ofthe United States, residingat vaminimum. j

With lthe above' recitedyobjects inl view,

Salem, in'the'county of Salem and State of NewfJersey, have inventednew and useful YImprovements in' Ventilating Fans, of which 'the following is a specification.

In carryingoutthe present invention it is my purpose to provideaV Ventilating fan and driving means therefor which will beL Vfound especially useful in the cars ofsubj Way trains to causek the circulations of air,v

in suchcars. v p

It is also my purpose toprovide a driving means for ventilatingrfans by whichthe fan may be drivenwitha minimum expenditure of commercial power and lwhich'will embrace the desiredvfeatures of simplicity, efficiency and durability.,

Furthermore, I aim t'oprovide a ventilated.

ing fan construction whereinthe fan l-may be held against operationfwhenever desired or necessary land wherein Vthe component" parts will be so arranged and correlated as` to reduce the possibilityv of' derangement to and others of asimilar nature,- whichl will appearV asy lthe `nature of `the invention is more fully set forth,'the invention consistsl in the'construction, combination ,and `arrangement of parts setl forth in and falling within the scope of the appended claims. y

In the accompanying drawings:

kFigure 1 is a fragmentarysectlonal View through the roof of the carr of a subway train, sho-wing my improved Ventilating fan v of the 'Y installed therein. Y

' Figure 2 is a bottom planl view same.

Figure 3 is a sectional view on the line a subway car or other vcar that it is desired4 to ventilate by means of my improved 'apparatus, or otherwise secured-to thek under side of thetop or ceiling 1. Extending through the housing2 isa vertical shaft 3 and Afastened to the upper end of the Vshaft 3 above' while 2 designates a housing bolted theitopfl vofthercar are propeller blades 4,

air 'impingesQ-upon vthe blades 4 and scimpartsrotary Jmotion yto the shaft. 3, thereby revolving the Vfan lblades v5 so .that they fan continues to` operate to :ventilate the car as long,V .asy the latter yisgin mo-tion, incident 'to` `WhileQfiXedtothe lower end ofthe shaft 3. within the l'carvand below the housing 2 are fan blades 5.',c-,As the car travels along the.

the airstriking lthe propeller blades 5 andl v revolving the latter.

'.Within the housing 2 Y y isan electric lmotor Y 6 Yof any"suitable-,construction connected .in an; .-,elect-ricfl circuit l17: yincluding af suitable l source ofelectrical energyand a switch y8.

In'otorY 6. is connected lwith the'shaft 3 yin some lsuitable manner,jand vwhen ener.-

gized acts to rotate the k'fain bladesy 5 inde-` pendentlvofathe propeller blades 4, thereby permitting the fan blade'sito beoperated for standstill..l v-

lAt times it may fan blades 1.5 against rgota'tionv under i the action ofthe blades 'g4-:fwhen the cargis in moti-on,zand for this reason providea-{suitablefbrake 'mechanism In the preferred" 'form of my invention the brake mechanism embodies abrake-drum v9 fixed to the shaft 3 immediately above.y ,the hubv of the blades 5 Vand, brake shoes 1,0,.--10y arrangedV upon opposite sides of the brake drum 9 and having their inner ends arranged in jnXtaposition to the drum 9 to engage the latter,-

and their outer ends fixed to yvertical varms 11-11, respectively, that depend from the top or ceiling 1. In the present instance theupper ends lof the arms 11 are pivotally connected withl blocks 12,'respectively that yare fastened to the under side of the top 1, while to the lower end ofone of the arms 11 is pivotally fastened one endof al rod 13, Athe other end of which extends through a slot formed in the lower end, of the other arm 11. Rotatablymounted-in the free end lever lfconnected with one end of a. cord 16 or other operating element. Thus, when the cord 16 is pulled, the cam 14 is rotated to swing the arms 11-11 towardeach other through the medium of the rod 13, 'thereby -ventilating purposes when the car. is at yal l 12' be desired to vhad the g vof thel rod 13 is a lcam 14`provided with a i moving the brake shoes 10--10 into engagement with the drum 9 to hold the shaft v3v againstrotation under the raction 0f the fanV blades 4.

i ,In` 'my present construction the innen ends of the brake shoes 10-10 are formed with slots 17'through which extend pins 18 fastened vto the bottom of the housing 2 and surrounding these pins 18, respectively, are springs 19 that are interposedbetween the lower end of the housing 2 and the upper surfaces of the brake shoes 10, thereby maintaining the brake shoes in proper positions with respect to the drum 9. l

In the modified form of the invention illustrated in Figures 5 and 6 of the drawings I dispense with the brake shoes 10-10 and the arms 11 and associated parts and employ a brake mechanism which embodies a drum 20 fixed to the shaft 3 and a brake hand 21 surrounding the drum 20. This band 2 1 is pivoted at one point, as at 22, and yat a diametrically opposite point is formed with outturned lugs 23-2LL To the lug 23 is pivoted one end of a pin 25, the other end of which extends through the slot formed in the lug 24.A Upon the last mentioned end of the pin 25 is rotatably mounted an operating cam 26 provided with a lever 27 which, in turn, is connected with an operating cord 28 embodying two runs 29 and 30, respectively, thiscord 28 being trained over a pulley31. Thus, when the run 29 of the cord 28 is turned in the direction of the arrow in Figure 6, the cam 26 is operated to expand the brake band 2,1 and so release the drum 20, whereas when the run 30 is pulled in the direction of the arrow in Figure' 6 of the drawings the cam 26 is operatedv to contract the band 21 about the drum 20, thereby holding the shaft 3 against rotation.

While I have herein shown and described one preferred form of my invention by way of illustration, Iwish it. to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modifications and variations maybe made within the scope of the claims and without departing from the spirit of my invention.

Having thus described the invention, what is claimed'as new, is

1. In Ventilating apparatus for motor vehicles, a vertical shaft extending through the top of the vehicle, fan blades lon the inner ends of said shaft, propeller blades on the outer end of said shaft, rotatable bythe action of the air in the travel of the vehicle to rotate the fan blades withinthe vehicle, a housing fastened tothe under side of Vthe top of' the vehicle and encasing the major portion of said shaft and a motor within said housing connected to said shaft tov drive the latter independently of said propeller blades.

2. In Ventilating ap aratus for motor vehicles, a vertical sha t extending through the` top of the vehicle, fan blades on the innerV ends of said shaft, propeller blades on the outer end of said shaft, rotatable by the action of the air inthev travel of the vehicle to rotate the fan blades within the vehicle, a housing fastened to the under side of the top of the vehicle and encasing the `major portion of said shaft, a motor within said housing connected to said shaft to drive the latter independently of said propeller blades, and brake mechanism associated with the inner en d of said shaft immediately below said housing to hold the said yshaft against rotation. f l

In testimony whereof, I affix myv signature.

WILLIAM BUCCUTO.
